A building should provide a pleasant, efficient and healthy environment for its occupants. Its primary purpose should be to protect from adverse conditions found outside; but in doing so, not loose the beneficial conditions found outside. If a building is properly planned and built well, these aims can be achieved. In most situations, buildings should satisfy the following:
· Buffer the impact of adverse external conditions (e.g. extremes of temperature, wind, moisture).
· Make use of natural light during the day (with windows, skylights, reflective interior surfaces, etc).
· Provide appropriate artificial light (without glare, with appropriate intensity and wavelengths, etc).
· Maintain good air quality inside (e.g. through ventilation, indoor plants).
· Minimise pollutants/toxins (e.g. fumes, dust).
· Control acoustics (stop unwanted noise; avoid interference/distortion of desirable noise, etc)
· Provide unimpeded movement and access to all areas.
· Provide rapid response to environmental controls (e.g. ability to raise or lower temperature quickly, ventilate rapidly if necessary).
DANGEROUS BUILDING MATERIALS
Some construction materials have no known impact on a person’s health, but others can have a very serious impact.
One of the best examples of undesirable building material would be Asbestos.
Though used widely in the mid 20th century, it is now widely recognised that asbestos can cause cancer. In 1979, James Hardie Industries made a conscious decision to cease the company’s heavy reliance on asbestos based products. The wide use of asbestos by other companies in the USA actually led to the downfall of those companies.
Research was undertaken around this time to develop asbestos free fibro cement, and new improved fibro cement was released onto the market by James Hardie in 1981. Despite the actions of Hardie such a long time ago, the legacy of asbestos has still plagued them with legal compensation challenges well into the 21st century.
Apart from this legal and commercial side to the asbestos story, there is also a tragic personal side. People exposed to asbestos decades ago continue to develop asbestos related illnesses, and all too often, not only the quality of life diminishes, but lives are lost.
